[0024] With the development of cloud computing applications, informatization has gradually covered all areas of society, and communication equipment has developed rapidly. As users' demand for broadband continues to increase, the bandwidth of single boards is growing. Single board external jumpers have emerged. Through external cable routing, signal loss is reduced, interference between signals is reduced, and the signal stability of the entire single board system is improved. However, the existing external cable routing is relatively messy and it is impossible to plan the routing path.

[0025] In view of this, the embodiments of the present application provide a printed circuit board and electronic equipment, which can use a wire harness structure to constrain the routing path of the cable, prevent the cable from being disordered or bulging, and is more conducive to the heat dissipation of the cable, thereby reducing the loss of heat dissipation capacity inside the single-board system. In addition, the cable is abutted against the outer wall of the wire harness structure, the structure is simpler, the operation is more convenient, and the wire harness structure can be made smaller, reducing the space occupied by the circuit board body.

[0026] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, a printed circuit board and an electronic device proposed in an embodiment of the present application, the printed circuit board includes:

[0028] A circuit board body having at least two circuit elements;

[0029] A cable 3, connecting two circuit elements; and

[0030] The cable 3 abuts against the outer wall of the cable harness structure 1 so as to adjust the routing path of the cable 3 between two circuit elements through the cable harness structure 1 .

[0031] In the technical solution adopted in this embodiment, the two circuit elements in the circuit board body can be electrically connected together by the cable 3 arranged outside the circuit board body to realize signal interconnection. Moreover, the cable 3 is arranged on the outside of the circuit board body, which saves the number of layers of the circuit board body, reduces the signal loss and interference between signals, and improves the signal stability of the entire single-board system. In addition, the harness structure 1 can constrain the routing path of the cable 3, prevent the cable 3 from being disordered, bulging, etc., and is more conducive to the heat dissipation of the cable 3, thereby reducing the internal heat dissipation capacity loss of the single-board system. In addition, the cable 3 is abutted against the outer wall of the harness structure 1, the structure is simpler, the operation is more convenient, and the harness structure 1 can be made smaller, reducing the space occupied by the circuit board body. At the same time, the harness structure 1 is used to plan the routing path of the cable 3, which can prevent the cable 3 from blocking the screw holes on the circuit board body, and then prevent the cable 3 from being damaged when the screws are locked, thereby reducing the risk of production and installation.

[0032] Specifically, the printed circuit board includes a circuit board body, a cable 3 and a wiring harness structure 1. The circuit board body has at least two circuit elements or circuits.

[0033] The cable 3 is used to connect the above-mentioned circuit elements or circuits to realize signal transmission and interconnection. The cable 3 can be a copper wire or an aluminum wire or a copper-aluminum composite cable 3, which is not limited here.

[0034] The harness structure 1 is used to plan the routing path of the cable 3. It is understandable that the cable 3 abuts against the outer wall of the harness structure 1, and then the routing of the cable 3 is changed by the harness structure 1. In one embodiment, the harness structure 1 can be a harness column or a harness plate, which is not limited here.

[0035] For example, refer to Figure 3 In one embodiment of the present application, the outer wall of the wire harness structure 1 has a limiting portion 11, and the cable 3 passes through the limiting portion 11 to limit the position of the cable 3 in the thickness direction of the circuit board body. In this way, the limiting portion 11 can be used to guide and limit the cable 3, preventing the cable 3 from sliding along the outer wall of the wire harness structure 1 in a direction away from the circuit board body and detaching from the wire harness structure 1, thereby improving the reliability of the wire harness structure 1 in planning the path of the cable 3. In one embodiment, the limiting portion 11 can be a limiting groove or a limiting protrusion, which is not limited here.

[0036] For example, refer to Figure 3 In one embodiment of the present application, the wiring harness structure 1 includes a limiting plate 12 and a support column 13, the support column 13 connects the limiting plate 12 and the circuit board body, and the outer diameter of the support column 13 is smaller than the outer diameter of the limiting plate 12 to form a limiting portion 11 between the limiting plate 12 and the circuit board body.

[0037] Specifically, the cable harness structure 1 includes a limit plate 12 and a support column 13. The limit plate 12 is arranged on one side of the circuit board body and is connected to the circuit board body through the support column 13, thereby realizing the fixation of the limit plate 12. As an optional method, the limit plate 12 and the support column 13 are integrally formed, so that the connection strength of the limit plate 12 and the support column 13 can be guaranteed. Of course, in other embodiments, the support column 13 and the limit plate 12 can also be assembled separately, which is not limited here. In one embodiment, the outer diameter of the support column 13 is smaller than the outer diameter of the limit plate 12 to form a limit portion 11 between the limit plate 12 and the circuit board body. It can be understood that a limit groove is formed between the limit plate 12 and the circuit board body, and the cable 3 is placed in the limit groove, and the cable 3 is limited by the inner wall of the limit groove. That is to say, while realizing the fixed connection between the limit plate 12 and the circuit board body, the cable 3 can be limited, the structure is simple, and the production is convenient. Optionally, the support column 13 can be a cylinder or an elliptical cylinder, which is not limited here.

[0038] For example, refer to Figure 3 In one embodiment of the present application, the harness structure 1 further includes a bottom plate 14, a support column 13 connects the limit plate 12 and the bottom plate 14, the bottom plate 14 is connected to the circuit board body, and a limit portion 11 is formed between the limit plate 12 and the bottom plate 14. In this embodiment, the bottom plate 14 is provided to increase the contact area with the circuit board body, and the reliability of fixing the harness structure 1 on the circuit board body can be improved. In one embodiment, the bottom plate 14 and the circuit board body are connected by bolts.

[0039] Illustratively, in one embodiment of the present application, the limit plate 12, the support column 13 and the base plate 14 are integrally formed, which can reduce the number of connecting components used and improve the connection strength; and / or, the base plate 14 is welded to the circuit board body, which can improve the connection stability between the wiring harness structure 1 and the circuit board body.

[0040] For example, refer to Figure 3 In one embodiment of the present application, a guide groove 15 is provided on the side of the bottom plate 14 facing the circuit board body, and the guide groove 15 is used for the flow of molten solder. When the bottom plate 14 is welded to the circuit board body, solder needs to be placed between the bottom plate 14 and the circuit board body, and the solder melts and solidifies to fix the bottom plate 14 and the circuit board body together. By providing the guide groove 15 on the bottom plate 14, the melted solder can flow along the guide groove 15, thereby improving the uniformity of the distribution of the solder on the bottom plate 14, and thus improving the firmness of the welding between the bottom plate 14 and the circuit board body.

[0041] For example, in one embodiment of the present application, a plurality of guide grooves 15 are provided, and the plurality of guide grooves 15 are arranged to intersect. In this way, by providing a plurality of guide grooves, the solder can flow to different positions, further improving the uniformity of the solder distribution. Moreover, the solder can flow between different guide grooves 15, improving the uniformity of the distribution of the solder in different guide grooves 15.

[0042] For example, refer to Figure 1 , Figure 3 as well as Figure 4 In one embodiment of the present application, the printed circuit board further includes a wire pressing structure 2, which is disposed on the circuit board body, and the cable 3 is pressed between the wire pressing structure 2 and the circuit board body.

[0043] Specifically, in areas where the cables 3 are concentrated or overlapped, they often exceed the surface height limit of the circuit board body. To this end, in this embodiment, a wire pressing structure 2 is provided, through which the concentrated or overlapped cables 3 can be compacted or compressed, the overlapping height can be reduced, and the subsequent cable 3 route planning can be facilitated. In one embodiment, the wire pressing structure 2 can be an elastic sheet. Of course, other structures that can apply pressure to the cables 3 toward the circuit board body can also be used, which are not limited here.

[0044] Exemplarily, in one embodiment of the present application, at least two wire harness structures 1 are provided, and the wire pressing structure 2 includes a spring, which connects the two wire harness structures 1 and is tensioned between the two wire harness structures 1 to press the cable 3 against the surface of the circuit board body.

[0045] In this embodiment, the wire pressing structure 2 includes a spring, which connects the two wire bundling structures 1. The spring between the two wire bundling structures 1 is tensioned and pressed on top of the cable 3, thereby applying pressure to the cable 3, pressing the superimposed or concentrated cables 3 onto the surface of the circuit board body, thereby lowering the height of the surface of the circuit board body.

[0046] For example, in one embodiment of the present application, the spring is an annular structure, so that the area of ​​the spring pressing on the surface of the cable 3 can be increased, the uniformity of the pressure of the spring on the cable 3 can be improved, and the cable 3 can be prevented from being loosely compressed at individual positions, thereby improving the effect of the spring compressing the cable 3.

[0047] For example, in one embodiment of the present application, the spring has two free ends, and the two free ends are detachably connected. In order to facilitate the assembly and tensioning of the spring on the two harness structures 1, the spring has two detachably connected free ends. In other words, the two free ends can be disassembled and separated, and the spring can be installed on the two harness structures 1; the two free ends can be combined and locked, and the spring can be tensioned between the two harness structures 1.

[0048] For example, refer to Figure 5 In one embodiment of the present application, the printed circuit board further includes a first buckle 41 and a second buckle 42 that are snap-connected, wherein one of the two free ends is provided with the first buckle 41, and the other of the two free ends is provided with the second buckle 42, and the two free ends are detachably connected through the first buckle 41 and the second buckle 42. It can be understood that the first buckle 41 and the second buckle 42 are snapped together to fix the two free ends; the first buckle 41 and the second buckle 42 are separated to separate the two free ends. Through the arrangement of the first buckle 41 and the second buckle 42, the structure is simple and convenient for disassembly and assembly.

[0049] Exemplarily, in one embodiment of the present application, an insulating layer is provided on the outer wall of the wire harness structure 1 and / or the wire pressing structure 2. In order to prevent the cable 3 from leaking electricity and establishing an electrical connection with the wire harness structure 1 and / or the wire pressing structure 2, an insulating layer is provided on the outer wall of the wire harness structure 1 and / or the wire pressing structure 2, thereby isolating the current on the cable 3. In one embodiment, the insulating layer can be a rubber sleeve or a plastic sleeve, etc.
